WPF 捕获系统主题改变

通过System.Windows.Interop

using System.Windows.Interop;// this is Window 可以写在构造方法里 this.SourceInitialized += Theme.ThemeManager.Window_SourceInitialized;// see "https://stackoverflow.com/questions/13660976/get-the-active-color-of-windows-8-automatic-color-theme"void Window_SourceInitialized(object sender, EventArgs e){ IntPtr hwnd; if ((hwnd = new WindowInteropHelper(sender as Window).Handle) == IntPtr.Zero) throw new InvalidOperationException("Could not get window handle."); HwndSource.FromHwnd(hwnd).AddHook(WndProc);}const int WM_DWMCOLORIZATIONCOLORCHANGED = 0x320;// see "https://stackoverflow.com/questions/13660976/get-the-active-color-of-windows-8-automatic-color-theme"IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled){ switch (msg) { case WM_DWMCOLORIZATIONCOLORCHANGED: /* * Update gradient brushes with new color information from * NativeMethods.DwmGetColorizationParams() or the registry. */ return IntPtr.Zero; default: return IntPtr.Zero; }}

这个也可以捕获系统颜色主题改变 也是WM_DWMCOLORIZATIONCOLORCHANGED
